2.2 Antennas
Connect cellular antennas to the router to main (ANT) and diversity (DIV) SMA connectors
on the front panel. For WiFi models, connect WiFi antennas to the router to
WIFI1
and
WIFI2
R-SMA connectors on the right panel. Connect the GNSS antenna to the router to GNSS SMA
connector on the right panel between the WiFi antennas.
Only run the router with a cellular antenna connected to the main antenna connector, as
the energy from the transmission is effectively reflected by the open end and can damage
the equipment.
Recommended tightening moment for screwing the antenna to the SMA connectors is 0.9 Nm.
The diversity antenna improves the radio capability of the router at low signal strength.
2.3 Ethernet Interfaces
The panel socket of RJ45 is used for Ethernet interface. The pinout of the socket is shown
in Figure 14 and described in Table 6 .
